Decorative case

ABSTRACT

A decorative case includes a box, a link, a gear transmission system, and a rotation disk. The rotation disk is rotated by operation of a motor, so that the ornament is rotated successively and automatically during a long period of time, thereby facilitating rotation of the ornament, and thereby saving the manual work. In addition, the light emitting members disposed in the ornament light continuously and blink intermittently, thereby enhancing the aesthetic quality of the ornament. Thus, the decorative case is rotated successively and can emit light outward simultaneously.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a decorative case, and moreparticularly to a decorative case that is rotated successively and canemit light outward simultaneously.

2. Description of the Related Art

A conventional decorative case comprises a housing, a rotary diskrotatably mounted on the housing, and an ornament mounted on the rotarydisk to rotate therewith. The rotary disk is usually rotatedmechanically in a wind-up manner, so that the rotary disk is onlyrotated during a short period of time, and movement of the ornament willstop when the rotary disk stops rotating, thereby greatly decreasing theamusement effect of the conventional decorative case. In addition, theornament cannot emit light, thereby greatly limiting the versatility ofthe conventional decorative case.

SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided a decorativecase, comprising a box, a link pivotally mounted in the box, a geartransmission system mounted in the box and having a drive gear rotatablymounted in the box and a drive shaft mounted on the drive gear to rotatetherewith and pivotally connected to a first end of the link to pivotthe link, and a rotation disk rotatably mounted on the box and having adriven shaft extended through the box and connected to a second end ofthe link to move therewith so that the rotation disk is rotatable bypivot of the link.

The primary objective of the present invention is to provide adecorative case that is rotated successively and can emit light outwardsimultaneously.

Another objective of the present invention is to provide a decorativecase, wherein the rotation disk is rotated by operation of the motor, sothat the ornament is rotated successively and automatically during along period of time, thereby facilitating rotation of the ornament, andthereby saving the manual work.

A further objective of the present invention is to provide a decorativecase, wherein the light emitting members disposed in the ornament lightcontinuously and blink intermittently, thereby enhancing the aestheticquality of the ornament.

Further benefits and advantages of the present invention will becomeapparent after a careful reading of the detailed description withappropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a decorative casein accordance with the preferred embodiment of the present inventioncomprises a box 10, a link 40 pivotally mounted in the box 10, a geartransmission system 23 mounted in the box 10 and having a drive gear 231rotatably mounted in the box 10 and a drive shaft 232 mounted on thedrive gear 231 to rotate therewith and pivotally connected to a firstend of the link 40 to pivot the link 40, and a rotation disk 30rotatably mounted on the box 10 and having a driven shaft 32 extendedthrough the box 10 and connected to a second end of the link 40 to movetherewith so that the rotation disk 30 is rotatable by pivot of the link40.

The box 10 has an inside having an upper portion formed with an annularchamber 11 for mounting the gear transmission system 23 and the link 40.The chamber 11 of the box 10 is defined by an annular wall 16. The box10 has a top face having a central portion formed with a circular hole12 and a periphery formed with a substantially arc-shaped guide slot 13.

The decorative case further comprises a transmission mechanism 20mounted in the chamber 11 of the box 10 and including a motor 22connected to the gear transmission system 23 to drive and rotate thedrive gear 231 of the gear transmission system 23, and a support disk 21secured to the box 10 to support the motor 22 and the gear transmissionsystem 23. The support disk 21 of the transmission mechanism 20 issecured to a bottom of the annular wall 16 of the box 10. The supportdisk 21 of the transmission mechanism 20 has a central portion formedwith a protruding hollow support post 211. The drive shaft 232 of thegear transmission system 23 is located on a periphery of the drive gear231 so that the drive shaft 232 is rotated with the drive gear 231eccentrically.

The rotation disk 30 has a central portion formed with a protrudinghollow rotation shaft 31 extended through the circular hole 12 of thebox 10 and rotatably mounted on the support post 211 of the support disk21. The driven shaft 32 is located on a periphery of the rotation disk30 and slidably mounted in the guide slot 13 of the box 10.

The link 40 is substantially arc-shaped. The first end of the link 40has a first pivot hole 42 mounted on the drive shaft 232 of the geartransmission system 23, and the second end of the link 40 has a secondpivot hole 41 mounted on the driven shaft 32 of the rotation disk 30.

The decorative case further comprises a plurality of light emittingmembers 55 mounted in the support post 211 of the support disk 21 andpartially protruded outward from the rotation disk 30, a bottom cover 50secured to a bottom of the box 10, a battery housing 52 mounted on thebottom cover 50 for receiving at least one battery (not shown), acircuit board 53 mounted on the bottom cover 50 and electricallyconnected to the battery housing 52, and a control switch 51 mounted onthe bottom cover 50 and connected between the circuit board 53 and thebattery housing 52 to control operation of the circuit board 53. Thecircuit board 53 is electrically connected to the motor 22 of thetransmission mechanism 20 and the light emitting members 55 by electricwires 54. The rotation disk 30 has a passage 34 to allow passage of thelight emitting members 55.

Referring to FIGS. 1-4, an ornament 60 is secured on the rotation disk30 to rotate therewith, and the light emitting members 55 are disposedin the ornament 60. When the control switch 51 is turned on, the lightemitting members 55 light and blink, while the motor 22 of thetransmission mechanism 20 is operated to drive the drive gear 231 whichrotates the drive shaft 232 which pivots the link 40 which drives thedriven shaft 32 to rotate the rotation disk 30 so as to rotate theornament 60. At this time, the driven shaft 32 of the rotation disk 30is limited by the guide slot 13 of the box 10, so that the rotation disk30 is rotated smoothly and stably.

As shown in FIG. 5, the decorative case further comprises a hanging hook14 mounted on a periphery of the box 10 for hanging smaller ornamentalitems (not shown).

Accordingly, the rotation disk 30 is rotated by operation of the motor22, so that the ornament 60 is rotated successively and automaticallyduring a long period of time, thereby facilitating rotation of theornament 60, and thereby saving the manual work. In addition, the lightemitting members 55 disposed in the ornament 60 light continuously andblink intermittently, thereby enhancing the aesthetic quality of theornament 60.
